Jill's twin brother, Jack, was found abandoned in 1965, at the age of 21 months, outside of McCrory's Variety Store on Broad Street in Atlantic City, New Jersey. When Jack was found, authorities believed him to Paul Fronczak, a baby who had been kidnapped almost 2 years previously, from a Chicago hospital, a day after his birth.
Jack was raised as Paul and it wasn't until 2015, after taking a DNA test, that he found out his true identity: Jack Rosenthal. At that time he also learned that he had a twin sister, Jill, who had gone missing around the same time he had been found abandoned in 1965.
The real Paul was identified by DNA in 2019 as Kevin Baty. He passed away in 2020.
Jill's whereabouts are unknown.
